LIFESPAN

The lifespan of a piston pressure switch depends on many factors. Minimum and maximum pressures,

Cycle speed, load changes, hydraulic vibrations, the load (amp.) On the electrical switch, etc.

If there are special requirements for the pressure switch, we can use many years of experience

Material pairings, processing methods and manufacturing tolerances targeted and flexible to the most varied

Meet requirements.
